The thermo hygrometer is used to measure and store environmental data such as temperature, humidity, illuminance, CO2 content and TVOC concentration. The thermo hygrometer also calculates the dew point, absolute humidity and the water vapor content in the air. The thermo hygrometer is used for stationary monitoring of laboratories, greenhouses, medicine and food stores, museums, etc.
With its hydrogen-selective sensor, the air quality meter can detect the smallest leaks with a very low leak rate. Containers or lines that do not contain hydrogen can also be checked for leaks with the air quality meter if they are filled with test gas containing hydrogen and then checked for leaks.
